The scale insect Dactylopius coccus produces the brilliant red-coloured carminic acid to deter predators. Up to 100,000 scale insects need to be collected and processed to make a kilogram (2.2 lbs) of cochineal dye. [89] A similar number of lac bugs are needed to make a kilogram of shellac, a brush-on colourant and wood finish. [90]
The pitch is nearly constant, the sound is continuous to the human ear, and cicadas sing in scattered groups. In addition to the mating song, many species have a distinct distress call, usually a broken and erratic sound emitted by the insect when seized or panicked.
Swarming insects must detect the wing sounds of conspecifics in order to identify potential mates, and do so by using vibrations present in the air. [3] The antennal Johnston's organ in swarming Diptera (e.g. midges and mosquitos ) may contain tens of thousands of scolopophorous sense cells, which are grouped by two's or three's into individual ...

Click beetle larvae, called wireworms, are usually saprophagous, living on dead organisms, but some species are serious agricultural pests, and others are active predators of other insect larvae. Some elaterid species are bioluminescent in both larval and adult form, such as those of the genus Pyrophorus .
It was believed, mainly on the authority of Maria Sibylla Merian, that this process, the so-called lantern, was luminous at night in the living insect. Carl Linnaeus adopted the statement without question and coined a number of specific names, such as laternaria, phosphorea and candelaria to illustrate the supposed fact, and thus propagated the ...
In evolutionary terms, the split between the Caelifera and the Ensifera is no more recent than the Permo-Triassic boundary; [12] the earliest insects that are certainly Caeliferans are Eolocustopsis of family Eolocustopsidae from the latest Permian (Changhsingian) of the Beaufort Group, South Africa, [13] followed by Locustavidae and ...
